Welp. I tried reinstalling Sailfish in accordance to the guide; I unfortunately end up with this error;
```>> fastboot -s HQ615S5435 flash oem_a ./SW_binaries_for_Xperia_Android_11_4.19_v9a_lena.img
Sending 'oem_a' (819200 KB)                        FAILED (remote: 'Requested download size is more than max allowed
